Questions & Answers about seito ga robotto o tameshita.

Why is the word order 生徒 が ロボット を 試した instead of something like English The student tested the robot?

Japanese usually puts the verb at the end of the sentence.

So this sentence follows the common pattern:

• 生徒 = student
• が = marks the subject
• ロボット = robot
• を = marks the direct object
• 試した = tested / tried

So the structure is:

subject + object + verb

That is very normal in Japanese.

What do が and を do in this sentence?

They are particles, and they show the role of each noun in the sentence.

• が marks the subject: the one doing the action
• を marks the direct object: the thing receiving the action

So here:

• 生徒が = the student is the one doing the testing
• ロボットを = the robot is what is being tested

Without these particles, it would be much harder to tell who did what.
